I dont know what the NSW rules say but the Victorian ones have a few interesting things.
"training flight approach", in relation to an aerodrome, means a planned descent to, or in the immediate vicinity of, a runway at the aerodrome, whether or not the aircraft touches the runway, during a flight undertaken for the training or testing of a person as a pilot or member of a flight crew.
Does this mean that an approach for maintaining proficiency once trained does not attract a fee?
(2) If an aerodrome operator fixes a fee under this section, a notice setting out the fee must be published in the Government Gazette and in—
(a) a daily newspaper circulating generally in the State; or
(b) a periodical publication prescribed by the regulations.
How many aerodromes have advertised their fees in a daily newspaper and the Government Gazette?
